Part of the Holly Recreation Area, the trail system consists of three main loops, North, West, and East.

The Holdridge Trail system's flagship feature is the east loop, a 15.5 mile advanced trail, Gruber's Grinder. It is very technical, much like Highland Recreation Area's mountain bike trails, and should be ridden by newcomers with caution.

The west and north loops are more accessible yet still quite fun, and the tech loop contains skinnies, drops, and rock and log piles for those who enjoy riding technical features.
